Syntax for selecting vertices when object is variable

[samuel-poznak]

Hello all,

I'm reasonably new to Maya, and I'm working on a fairly specific project.

For the project, I need to select the vertices of objects individually. Typically, this is fairly easy using something like select -r pCube.vtx[3].
But, the names of these objects are variable and stored in array I obtain using the command:
string $dataset[] = ls data\_*;

I can still select the whole object using select -r $dataset[1], but I'm running into an issue when I try to select the individual vertices.

So far, I have tried select -r $dataset[1].vtx[3], but obviously that brings up a syntax error.

Is there any way to do this? Or perhaps a workaround?

Thanks
